How to Display IB Device Information

You can use the prtconf command to display general information about IB devices. For example:

$ prtconf
    pci, instance #0
        pci15b3,5a44, instance #0
             ibport, instance #253
             ibport, instance #254
             ibport, instance #255
    .
    .
    .
    ib, instance #0
        ioc, instance #243
        ioc, instance #244
        ioc, instance #245
        ioc, instance #246
        ioc, instance #247
        ioc, instance #248
        ibgen, instance #249

In the preceding example, pci15b3,5a44 refers to an IB HCA.

Use the following steps to display specific IB device information.

1. Become superuser.

2. Display IB fabric information.

   For example:

   # cfgadm -a Ap_Id Type Receptacle Occupant Condition ib IB-Fabric connected configured ok hca:1730000008070 IB-HCA connected configured ok ib::1730000007F5198 IB-IOC connected configured ok ib::1730000007F5199 IB-IOC connected configured ok ib::1730000008070,0,hnfs IB-HCA_SVC connected configured ok ib::1730000008071,0,sdp IB-PORT connected configured ok ib::1730000008072,0,sdp IB-PORT connected configured ok ib::1730000008071,8001,ipib IB-VPPA connected configured ok ib::1730000008072,8001,ipib IB-VPPA connected configured ok ib::ibgen,0 IB-PSEUDO connected configured ok #

   In the preceding example output, the components are described as follows:

   Ap_Id ib::1730000008072,0,sdp

   Identifies an IB Port device that is connected to port 2 and is bound to the sdp service.

   Ap_Id ib::1730000008072,8001,ipib

   Identifies an IB VPPA device that is connected to port 2, using a p_key value of 0x8001, and is bound to the ibd service.

   Ap_Id ib:: 1730000008070,0,hnfs

   Identifies an IB HCA_SVC device bound to the hnfs service.

   Ap_Id ib::1730000007F5198

   Identifies an IOC device.

   Ap_Id ib::ibgen,0

   Identifies a pseudo device.

3. Display specific IB device information.

   For example, for an IB VPPA device:

   # cfgadm -al -s "cols=ap_id:info" ib::1730000008072,8001,ipib Ap_Id Information ib::1730000008072,8001,ipib ipib #

   For example, for an IB HCA device:

   # cfgadm -al -s "cols=ap_id:info" hca::1730000008070 Ap_Id Information hca::1730000008070 VID: 0x15b3, PID: 0x5a44, #ports: 0x2, port1 GUID: 0x1730000008071, port2 GUID: 0x1730000008072 #

   The preceding output displays the number of ports and their GUIDs.
